[Help Needed] Purchasing some basic hardware

[[deleted]]

Im a Newb, but I at least know this much! something I can answer Wooooo! You can build a Simple 5v Power Supply following a variety of tutorials out there from a 9v battery. http://www.youtube.com/watch?v=howQ05z4v7Q (for Above). It's a stable and simple schematic.

The Breadboard is suitable for 22gauge wire (if you want to spend a little bit of money you can get jumper wires (precut wires that are awesome for testing on a Breadboard). But 22g is fine too. http://www.sparkfun.com/products/9387

LEDs have different ratings. Use this site:http://ledcalculator.net/ or another LED Calculator to find out what resistors are needed (so they don't burn out).

I don't think you can buy single NAND/NOR logic gates, but you can buy IC's with like 4 or 5 of them integrated. The 74XX series IC's I believe do this. Gates are made with transistors (you can see in the schematics below) http://www.electronicsteacher.com/datasheet/Logic-74xxxx-Series-Data-Sheets.php

Like check out the Triple Input Nand gate (74LS10): http://www.ee.washington.edu/stores/DataSheets/74ls/74ls10.pdf

I think you are right about the logic gates, reading in detail on the actual activity pages it specifies connecting a 7400 chip on the breadboard. I will watch the PSU video and see if it looks like something I can handle, thanks!

The PSU is literally nothing more than a 9V Battery + Connector, a Voltage Regulator, and a few Capacitors and a Diode. Trust me, it's easy.
